If it isn't you then who is to say that the person judging isn't removing value from you to reinforce their point of view.

Almost worse if it is you, then what is to say we aren't going to create a society of echo chambers, where you can tailor the internet to read what you want or expect it to read.

Comments should still remain, primarily, about freedom of expression even if most of that expression is just there to remind you of the illiteracy of the majority of the population.
